Hansen by Catherine Lievens

Love can heal even the worst of wounds.

Hansen has spent the past few years saving people. He likes his life, but there’s one thing missing—his mate. He yearns for that kind of connection, even though there’s nothing he can do to find the one person who’s destined to be his.
Evan has spent the past few years in a cage. The last thing he expected when he was taken out of it and used as leverage by a hunter was to find his long-lost best friend—and his mate. After everything he went through and the fact that he’s now a mutant, he’s not sure what he’s ready for, but he won’t let the hunters and the doctors win.
Hansen and Evan find their way to each other, but their fight won’t be over until all the labs are closed and the hunters are gone. The problem is that no one knows how to make that happen or how long it will take.

Or what will happen to the mutants and their loved ones in the meantime.
